Filed: 1954-02-18
Abstract: 750,841. Fasteners; anchor nuts; bolts. PACHMAYR, F. A. Feb. 18, 1954 [July 20, 1953], No. 4771/54. Classes 44 and 89 (1). A fastener, for securing inner and outer work members (e.g. metal plates 12, 11) together, comprises a tubular receptacle 16, Fig. 1, secured (e.g. by rivets 18 with the interpositioning of a spacer plate 19) to the inner plate 12, a rotatable headed stud 22 insertable into the receptacle through an opening 15 in the outer plate 11 and opening 20 in the spacer plate, a rotatable and axially displaceable nut 21 contained within the receptacle, the shank of the stud having diametrically opposed interrupted screw-threads 24 receivable between and rotatable into and out of mating engagement with correspondingly arranged interrupted screwthreads 27, Fig. 3, in the nut 21, shifting means operable upon rotation of the nut by the stud (e.g. when the two sets of threads are not correctly aligned) to displace the nut axially thereof into mating alignment of the stud and nut threads, and a spring 34 resisting such displacement of the nut. The. nut 21, Fig. 3, has diametrically opposed plain portions 28 in order that the stud may be axially slid into the nut. The shifting means comprise four diagonally disposed ribs 41, Fig. 1, in the base of the receptacle 16 which is polygonal in crosssection, the ribs coacting with four diagonally disposed recesses or grooves 40 in the bottom of the nut 21. Slidably, but non-rotatably mounted on the stud above the nut 21 is a detent disc 29 having on its lower surface ribs 30, Fig. 3, which coact with grooves 31 in the top of the nut. A stop member 32 on the detent engages in a recess 33 in the nut and the recess is formed with stop faces 34. This arrangement of the detent and nut permits the detent to be displaced one quarter of a turn with respect to the nut. The detent is urged into engagement with the nut and the nut grooves 40 into engagement with the ribs 41 by the spring 35 which engages between the detent and the spacer plate 19. A washer 38 and spring 37 having a bent end 39, Fig. 3, engaging in one of a pair of grooves 26 in the stud 22 serves to partially eject the stud when disengaged from the nut. The detent 29 releasably locks the stud to the nut when the threads are mated and also establishes the initial or releasable positions of the stud relative to the nut. If when inserting the stud into the nut the respective threads are not correctly aligned the rotation of the stud will cause partial rotation of the nut relative to the receptacle and by camming action between the ribs 41 and the grooves 40 the nut will be raised until the threads are aligned, whereafter continued rotation of the stud causes the stud threads to interlock with the nut threads.

Title: Improved motor vehicle having power steering apparatus and control system therefor
IPC: B62D6/00
Filed: 1957-02-13
Abstract: 814,496. Vehicle power steering. GENERAL MOTORS CORPORATION. Feb. 13, 1957 [March 1, 1956], No. 4954/57. Class 79(5) [Also in Groups XXXV and XXXVIII] A power steered vehicle has motionsensers such as an accelerometer measuring transverse acceleration and a rate of turn gyroscope measuring yaw which are used to modulate the action of a control element in the steering system. In one example in which the torque applied to a steering column 120, Fig. 1, upsets the balance of a resistance strain gauge bridge 126 controlling a hydraulic servo-system 122, the amplified electrical signal from the strain gauge is modulated by amplified electrical signals from a rate of turn gyroscope 128 and from a transverse accelerometer 130 mounted on the vehicle frame. The strain gauge bridge 126, gyroscope 128 and accelerometer 130 are energized by alternating current from a supply 124 and generate input voltages for the amplifier 132 which are in proportion to the magnitudes of the torque, acceleration or rate of turn and have a phase or polarity determined by the direction of the torque &c. The amplifier 132 includes a phase sensitive demodulator which delivers a rectified output corresponding to the algebraic sum of the input voltages. Controls 156 on the amplifier may adjust the relative influence of the acceleration or rate of turn on the output signal. The hydraulic servo-system comprises a pivoted armature 176 extending between spaced nozzles 178, 180 to vary the pressure at opposite ends of servo-cylinder 72 through valves 166, 168. The armature is mounted in a permanently magnetized core 174 and its movements are controlled through an electrical winding 160 connected to the output stage of the amplifier 132. In operation, the device may take over completely from the driver in the event of a skid on an icy road, the wheel being automatically steered by the rate of turn gyroscope to correct the vehicle spin. During cornering at speed the transverse accelerometer automatically reduces the effort of the servo-system so that the driver must exert a greater proportion of the steering effort and is thereby afforded an artificial feel.

Abstract: 1,204,086. Soluble copolyimides. KUREHA KAGAKU KOGYO K.K. 29 Jan., 1969 [1 Feb., 1968], No. 4974/69. Heading C3R. Soluble copolyimides are prepared from an aromatic diamine and a mixture of a major proportion of 1,2,3,4- and a minor proportion of 1,2,4,5-benzene tetracarboxylic acid dianhydrides. Specified diamines are 3,3<SP>1</SP>-diamino diphenyl ether, methane, sulphide and ketone. Polycondensation may be effected at -60‹ to 50‹ C. in a polar organic solvent e.g. N,N<SP>1</SP> - dimethyl acetamide or formamide, N - methyl pyrrolidone, dimethyl sulphoxide or pyridine to give a polyamide acid which may be treated with an imidizing agent, e.g. a molecular sieve or a mixture of pyridine, acetic anhydride and optionally benzene, to give a solution of the polyimide. The polyimide solutions may be used as a coating or adhesive for electric wire, for casting films or forming fibres by spinning into a non-solvent. The polyimide may be purified by precipitation in water-free benzene and redissolved in an organic polar solvent or sulphuric acid.
Patent GB-929890-A (GB)
Title: Improvements in or relating to apparatus for receiving permutation code groups of pulses
IPC: H04N21/2383
Filed: 1960-05-25
Abstract: 929,890. Pulse-code modulation systems. WESTERN ELECTRIC CO. Inc. May 25, 1960 [June 15, 1959], No. 4975/63. Divided out of 929,889.. Class 40 (5). In a system in which samples of a message wave are represented by code pulse groups which are transmitted without marker (i.e. synchronizing) pulses, the receiver includes means for detecting the occurrence of a predetermined pattern of code pulses which indicates that the receiver is incorrectly synchronized with the code pulse groups and for adjusting the phase of the receiver accordingly. The invention is described in relation to the system of Specification 929,889, in which alternate code pulses are inverted in order to prevent loss of timing information when transmitting television signals by P.C.M. In one embodiment, the synchronizing pulses in the television signal each occupy about 50 coding periods and the peak level of the pulses is represented by the group 0000000. If the receiver is incorrectly phased it develops the inverse group 1111111. When the correct group 0000000 is developed by the receiver, AND gate 71, Fig. 4, produces an output pulse to charge capacitor C 1  so as to drive transistor 74, which is normally non-conducting, further beyond cutoff. A sequence of the groups produces a cumulative effect. On the other hand, if the inverse group is developed, AND gate 72 causes capacitor C 2  to be charged, and when the number of repetitions of group 1111111 exceeds that of group 0000000 by a predetermined amount, transistor 74 conducts and opens switch 80 so as to block the passage of one pulse from 10 Mc/s. source 42 to divide-by-two timing- circuit 41. In other words, the phase of the receiver is adjusted by one pulse period. In the second embodiment, use is made of the fact that in the reflected binary code, which is used in the transmission of the telvision signals, the second most significant digit is a " 1 " for the central range of amplitudes represented by the code. Thus this digit should occur more often as a " 1 " than as a " 0." A circuit similar to that of Fig. 4 may be used to examine the appropriate digit channel signals, only one diode in each of gates 71, 72 being required. In the third embodiment, one code group is not used in representing the signal amplitude, and thus is only developed at the receiver if circuit 41 is wrongly phased. A circuit similar to that of Fig. 4 is used to detect the " forbidden " code group, and since a single occurrence of the " forbidden " word indicates incorrect phasing of circuit 41, the transistor 74 may be arranged to conduct after only a very small number of occurrences has been detected. Specifications 663,872, 679,725, 681,330 and 694,030 also are referred to.

The tie member may also be slotted at 54 to receive a portion of the cross member. The holes 36 may be provided with shoulders 37 (Fig. 10) to abut the cross members when in the final position. Cement may be applied at each joint to strengthen it. A tip brace 45 is slotted into member 14 for further rigidity. A preformed wall fairs in the leading edge of the wing as far as the main spar 14. Fabric or paper covers the trailing edge, and the ribs are shouldered at 44 to provide a flush joint between the material and the thicker preformed wall. The fuselage, seen in part in Fig. 3, is constructed on similar lines, having bulkheads 25 as cross members in holes 26 in the main frame 14. Longitudinal tie strips 32 are used, and a preformed skin is applied. Each cross member may be sized to fit only one hole, so that assembly from kit form is simplified.
